Title: Rotary head type magnetic video recorder and reproducer
Inventor: IWAZONO YOSHINORI
IPC: G11B15/087
Filed: 1980-11-19
Abstract: PURPOSE:To detect an index signal accurately at all times, by comparing the integration output of a rectangular pulse corresponding to a control signal in which the duty forming the index signal is changed and an opposing polarity pulse, respectively. CONSTITUTION:A playback control signal forming an index signal with the change in the duty via an amplifier 2 is processed at positive/negative polarity pulse separating circuits 3, 4, a missing signal correcting circuit 6, and an FF5. Then, a rectangular pulse (f) and an opposite polarity rectangular pulse (f') according to the duty are generated from the FF5 and they are respectively integrated at integration circuits 7, 9. When the integration outputs (g), (g') are compared at a comparison circuit 10 by taking the output (g') as a reference, the effects such as change in playback speed and ambient temperature are canceled with a section output (h) where the output (g) is smaller than the (g'), allowing to detect index signals accurately at all times.

Title: Thin film forming device
Inventor: KUROKAWA HIDEO
IPC: G11B5/85
Filed: 1983-09-07
Abstract: PURPOSE:To allow an uniform and reproduceable polymerizable film to be obtained by providing a plasma generating tube of which surface on an inner wall being coated with macromolecular insulation composed of the same constituent as monomer gas to reduce influence of etching function. CONSTITUTION:A plasma generating tube 17 into which inactive gas and monomer gas are introduced is supplied with a high frequency power through a high frequency coil wound on the circumference of the plasma generating tube to generate discharge. This discharge generates a radical and forms a polymerizable film and, also, it generates ions. The ions have an etching function and etches an inner wall of the plasma generating tube 17. If the inner wall of the plasma generating tube 17 is formed by macromolecular insulation of the same constituent as monomer gas, the gas constituent during discharge does not change even if the inner wall of the plasma generating tube 17 is subjected to etching. Thus, a stable and uniform polymerizable film can be obtained.

Title: Refrigerant flow divider
Inventor: TAIRA TERUHIKO
IPC: F25B39/00
Filed: 1990-06-22
Abstract: PURPOSE:To uniformly divide the flow of a refrigerant and to prevent lowering of heat exchange performance of a heat exchanger serving as a condenser by a method wherein a flow passage on-off valve for intercoupling first and second connection pipes and a small part is provided and the small part being finer than the second connection pipe running between a hollow body 2 and an outflow inflow pipe is located to the first connection pipe. CONSTITUTION:When a heat exchanger 15B is used as a condenser, a refrigerant flows in a reverse direction to that during vaporization, and a flow passage on-off valve 5 is in an opening state. In this case, since the first connection pipe 3 has a small part 3n being finer than a second connection pipe 4, a pressure loss of a refrigerant R at the small part 3n is high. When the refrigerant R flows out from a hollow body 2, it flows out through a second connection pipe 4, having a low pressure loss, to an outflow inflow pipe 3i. The second connection pipe 4 is located to the lower end part of the hollow body 2. At a heat exchanger 15B, the condensed refrigerant R is caused to smoothly flow out without residing in heat transfer pipes 6 and the hollow body 2. By changing a flow route for a refrigerant by opening and closing a flow passage on-off valve 5 according to a condensing period and a vaporizing period, a refrigerant is uniformly divided, and heat exchange performance of the heat exchanger 15B can be increased to a maximum.

Then, the reproduced image data is extracted based on the information and the image is reproduced.
